Abstract
Changing the index in the two output branches of a Y-branch optical waveguide in opposite directions, in amounts which are controlled by electrical signals applied to the branches, is used to control the chirp of the signal outputted from the Y-branch optical waveguide. In this manner, predetermined amount of chirp can be add to or subtract from an input signal to the Y-branch optical waveguide. The Y-branch optical waveguide can be fabricated using Group II-VI, Group III-V or Group IV material systems or using an insulating material, such as lithium niobate. The output branches of a semiconductor implemented Y-branch optical waveguide can be fabricated to each include a multiple quantum well for controlling the refractive index of that branch in response to an electrical signal.
